I must thank the tester of my webisites's security! He hacked it nicely and easily through tampering with 'htmlpage' variable's value!
Now i'am validating htmlpage's input value and i don't beleive its hackable any more! Please feel free to try whoever want to! Thnk you all for your patience with me and support provided! -- http://mail.python.org/mailman/listinfo/python-list
